Ingredients Needed

For the Cauliflower:

• 1 head of cauliflower (about 800g/1.75 lbs)
• 4 cloves of garlic

For the Sauce and Crunch:

• 100g (about 3.5 oz) sourdough bread
• 50g (about 1.75 oz) blanched almonds
• 1 x 460g (about 16 oz) jar of roasted red peppers

How To Make Jamie Oliver 5 Ingredients Roasted Cauliflower

1. Preheat the Oven: Set your oven to 180°C (356°F) so it has time to heat while you prep the ingredients.
2. Prep the Cauliflower: Trim off the outer leaves and stalk end, then slice the cauliflower into thick 3cm wedges. Lay them flat in a large roasting tray so they roast evenly.
3. Season and Roast: Drizzle the wedges with olive oil and a splash of red wine vinegar. Add a pinch of sea salt and cracked black pepper. Pop them in the oven for 35 minutes until golden and tender with crispy edges.
4. Toast the Bread Mix: When there’s about 15 minutes left on the cauliflower, grab a second tray. Tear your sourdough into rough chunks, peel the garlic cloves, and scatter everything along with the almonds. Roast them in the oven until they’re golden brown and fragrant.
5. Make the Romesco Sauce: After roasting, reserve a handful of almonds for topping. Add the rest to a blender with the toasted garlic and bread, along with the drained roasted red peppers. Add 2 tablespoons of olive oil and a splash of red wine vinegar. Blitz until silky smooth, adding a splash of water if needed. Season to taste.
6. Assemble and Serve: Spread the Romesco sauce onto your serving plate, top with the roasted cauliflower, and finish with the chopped reserved almonds for that extra crunch.
